Same problem here, I can't open any tif files ever since the last update. Not even the files created by AP for Ipad itself. Tried to do a stack of two tif files created from raws on the IPad just now. It shows them fine in the file selection dialog but as soon as I stack they are invisible. The document shows as 0*0 pixels.

Hi JGKK,
Welcome to Affinity Forums
I've not yet able to make the colours of the wheel disappear but I've managed to get them corrupted. Something isn't working quite right here. I'm checking a few more things and will log this to be looked at. Thanks for lettings us know.

Thanks, it happens mostly when I use the picker to select a custom range

Often when I use the HSL Tool the colors on the color wheel disappear. I use Affinity Photo in Full Screen on an Imac 5K 27" from late 2015. The colors reappear if I switch to a different App/Screen and than back to Affinity Photo. The Tool still works but you cant see your range. I reported this before in a reply but now I got around to take a screenshot of the behavior.

An option to make the Histogram visible/floating while doing any of the other adjustments. This would be useful for example when adjusting the levels or brightness tool and keeping it open while switching layers etc.

Before the restart after first writing this thread I tried to imported the raw photo from an SD card directly into the Apple photos app on the iPad too. The import itself worked but after it was finished it would show up square and very low res in the library and would not be editable. Definitely looks like an IOS Bug.

I've just downloaded a sample RAW from the Fujifilm X-H1 and I get the same results as you. Affinity Photo for iPad uses the Apple RAW engine built into iOS so it may be that Apple has to improve the support in iOS for that model before Photo will open it.

Preview on macOS may be opening an embedded JPEG preview. In the meantime you could use Adobes DNG converter to convert to a more generic DNG file.

Although I switched my X-H1 one to uncompressed raw I cant open the files in affinity photo on the ipad (ios 12.1, 11" Ipad pro). They show just fine in Preview on the Mac wich the compressed files didnt. When I import a file from Icloud into Affinity Photo on the Ipad I get a black screen and It says no camera Data at the top. Do you have any Idea what the problem could be?

One Bug has appeared where the color wheel in the HSL modul disappears at random points and i only see a black circle but it still works. It goes back to normal when I go to a different app and than back to Affinity Photo (Affinity is in full screen)

Otherwise performance with the new GPU support is definitely improved on my Imac with files that include several live filter layers.
